The Global Pressure and Temperature model. This model is an empirical model that provides the temperature and the pressure depending the latitude and the longitude of the station.
The Global Pressure and Temperature model is based on spherical harmonics up to degree and order of 9. The residual values of this model can reach 20 hPa for pressure and 10 ° C for temperature. They are significant for higher latitudes and small near the equator (Böhm, 2007)
